(HELP) with Autounattended and setupcomplete

I have sussusfully used cerberus modified OEM and Daz loader. but having another issue wich is very complex to me because I am not fimiliar with coding etc..

Problem is that I want to use autounattended for unattended installation of windows 7 but I also want to install some applications with etupcomplete.cmd I was able to do this but problem is that I need to install application on the base of architecture of installed OS I mean setup1x32.exe should be installed on 32 bit OS while setup1x64 could be installed on 64 bit OS.

doesn't it make my win image larger in this case? I have created an AIO Windows 7 DVD, everything works great I just want to run wpi after Windows Loader, I mean when Daz Loader reboots the syte,m wpi should come up immitiately after boot like it does in normal mode but this coomand will delete scripts directory isn't it?
